DISCUSSION
ISSUED AT 1225 AM CDT TUE SEP 16 2025
THE FORECAST AREA WILL REMAIN ON THE WESTERN PERIPHERY OF A
CLOSED LOW PRESSURE SYSTEM CENTERED OVER EASTERN NORTH CAROLINA
HEADING INTO TODAY. AREAS OF ASCENT ROTATING THROUGH THE REGION
WILL CONTINUE TO RESULT IN MAINLY ISOLATED TO SCATTERED SHOWERS,
ALONG WITH A STORM OR TWO. POPS FOR TODAY AND TONIGHT WERE
ADJUSTED UPWARDS TO INCLUDE MENTION OF AT LEAST SLIGHT CHANCE
PRECIP CHANCES ACROSS THE FORECAST AREA, THOUGH COVERAGE MAY BE
LESS THAN 20%.
ONCE AGAIN THIS AFTERNOON, WHILE OVERALL FLOW IS LACKING,
SOMEWHAT STEEP MID-LEVEL LAPSE RATES (AROUND 6C/KM), VERTICAL
TOTALS NEAR 30, AND CURRENT ADVERTISED ML CAPE VALUES BETWEEN
1500-2000 J/KG, COULD YIELD A STRAY STRONG STORM OR TWO CAPABLE OF
PRODUCING GUSTY WINDS ACROSS MAINLY NORTHWEST PORTIONS OF THE
FORECAST AREA.
THE REMAINDER OF THE FORECAST WILL SEE A PATTERN BREAKDOWN AS
CENTERS OF UPPER-LEVEL LOW PRESSURE OVER THE NORTHERN ROCKIES
AND THE EAST COAST WEAKEN. FLOW ACROSS THE CONUS SHOULD BECOME
ZONAL BY THE WEEKEND, WITH MORE AREAL COVERAGE OF SHOWERS AND
THUNDERSTORMS POSSIBLE AS THE WESTERN SYSTEM PIVOTS THROUGH THE
CENTRAL PART OF THE COUNTRY. AVERAGE TEMPS WILL STILL BE A LITTLE
WARMER THAN NORMAL - ABOUT 3 TO 5 DEGREES WARMER THAN NORMAL ON
MOST DAYS. /NF/
